Hmm, ellipsis could be <mn>, <mi> or <mo> depending on how it
was used.  In my experience, <mn> is the _least_ common use
I would expect, but the MathType guys had to pick something, I guess....

More interesting to me is that it seems wrong from a grammatical
point of view to have no operator between <mn>....</mn> <mi>A</mi>
It seems more correct to have a comma:  P.Q,R,...,A,B,C
but then some people may not want to see that extra comma?
[and in that case, they probably object violently! :> ]
Perhaps it should be hidden somehow?

That seems normal.

By "see" you mean in the xml source, as opposed to in some browser?
There're reasons to both love & hate mfenced.  It seems to sit
halfway between "Content" and "Presentation", and it gives a
headache to a CSS approach to presenting the math....
But, really the answer is: Whichever you prefer.
